ARYLPIPERAZINE COMPOUND AND PRODUCING METHOD THEREOF

摘要

PURPOSE: An arylpiperazine compound and a producing method thereof are provided. The arylpiperazine compound can label technetium and F-18 with no having disadvantages of prior arts. CONSTITUTION: The arylpiperazine compound is represented by formula (1), in which R is methanesulfonyl, paratoluenesulfonyl or trifluoromethanesulfonyl. A compound of formula (1a) is produced by treating a compound of formula (7) with mesyl chloride under triethylamine. A compounds of formula (1b) is produced by reacting a compound of formula (13) with sodium hydrogen and the compound of formula (7) to produce a compound of formula (14); and dissolving the compound of formula (14) in anhydrous anisole and reacting with anhydrous trifluoro acetic acid, in which the compound of formula (13) is produced by dissolving a compound of formula (9) into trifluoro acetic acid and reacting with triphenylmethanol to produce a compound of formula (10); reacting the compound of formula (10) with triethylamine and bromoacetyl bromide to produce a compound of formula (11); reacting the compound of formula (11) with triphenylmethanol under trifluoro acetic acid to produce a compound of formula (12); and reacting the compound of formula (12) with 3-bromopropionyl chloride. The formula (1b), (9) to (14) are described as in the description.
